Review on 🚲 Topeak ProPack Bike Seat Bag by Chip Palmer

have been using it for almost six months, below are the pros and cons. Relative simplicity - Looks cool and the reflective material offers some safety - Still like it despite loosening the screw. It happened that someone picked up my bag and, after finding a Blackberry in it, called my work number and the bag was returned. It doesn't fail immediately, but if you ride for more than an hour, the bag may fall off during that time. - My solution was to attach a zip tie to the seat rails and mounts, which saves me mental stress. You can hardly see it.
